What to watch

When O'Korn found his groove two weeks against Purdue – his only extended time on the field this season – he did so by taking advantage of Michigan's athletic and long tight ends against interior linebackers over the middle of the field. Zach Gentry and Sean McKeon had a combined eight catches for 130 yards and a touchdown in the game and were consistent targets throughout the second half. Bachie and Frey are active participants in Michigan State's top 20 rush defense but will have to maintain discipline if and when U-M goes to play-action. Purdue fell apart here and O'Korn – who was not hesitant with the football – had no problem taking advantage.

Frey is an active member of MSU's pass rush this season and O'Korn's overall pocket presence is still somewhat untested. He got better as the game wore on against Purdue, but had some struggles against pressure earlier in that game and against Florida. He has the ability to pull the ball down and run, but there are times when he looks like he's second-guessing what he should do against pressure. Bachie will need to be disciplined in case O'Korn leaks out and Frey has to get home with his pressures, as the more MSU heats up U-M's quarterback the better things will go for MSU on Saturday night.
